These three-dot tritium heavy duty night sights were created with the challenges of law enforcement and military duty in mind. With their yellow or orange photoluminescent paint outline and tall blade, the front sight increases visibility and quickens sight acquisitioneven in transitional lighting. The rear sight is black-outlined and specially shaped for faster front sight acquisition. Additionally, the front surface is steeply hooked to assist in emergency one-handed slide operation. The Hard Duty Night Sights are designed to shine—even in the most demanding conditions.
